NAME

       list_devices - list allocatable devices

SYNOPSIS

       list_devices [-s] [-U uid] [-z zonename] [-a [-w]]
	    -l | -n | -u [device] | [-l | -n | -u] -c dev-class

       list_devices [-s] -d dev-type

DESCRIPTION

       The list_devices utility lists the allocatable devices in the system according to specified qualifications.

       The  device  and all device special files associated with the device are listed. The device argument is optional and, if it is not present,
       all relevant devices are listed. If dev-class is present, devices belonging to the specified dev-class are listed. There is no default dev-
       class.

OPTIONS

       The following options are supported:

       -l [-c dev-class | device]    Lists  the  pathnames of the device special files associated with the device that are allocatable to the cur-
				     rent process.

				     If dev-class is specified, lists only the files associated with all devices of the specified device class.

				     If device is specified, lists only the files associated with the specified device.

       -n [-c dev-class | device]    Lists the pathnames of the device special files associated with the device that are allocatable to  the  cur-
				     rent process but are not currently allocated.

				     If dev-class is specified, lists only the files associated with all devices of the specified device class.

				     If device is specified, lists only the files associated with the specified device.

       -s			     Silent. Suppresses any diagnostic output.

       -u [-c dev-class | device]    Lists the pathnames of device special files associated with the device that are allocated to the owner of the
				     current process.

				     If dev-class is specified, lists only the files associated with all devices of the specified device class.

				     If device is specified, lists only the files associated with the specified device.

       -U uid			     Uses the user ID uid instead of the real user ID of the current  process  when  performing  the  list_devices
				     operation. Only a user with the solaris.device.revoke authorization can use this option.

       The following options are supported when the system is configured with Trusted Extensions:

       -a	      Lists attributes like authorizations, cleaning programs and labels associated with a device.

		      The list is a single line of semicolon (;) separated key=value pairs for each device in the format:

			device=device-name;type=device-type;
			auths=auths;clean=device-exec;
			device-attributes;
			files=device-list

		      where device-attributes is the contents of the reserved1 field of device_allocate(4). The field is colon (:) separated.)

		      See device_allocate(4) for a description of these attributes and their format.

		      The -a output has the following keys:

		      auths	Specifies the list of authorizations. The value is auths is described in device_allocate(4).

		      clean	Specifies the device cleaning script. The value is device-exec as described in device_allocate(4).

		      device	Specifies the device name. The value is device-name as described in device_allocate(4).

		      files	Specifies the device file paths. The value is device-list as described in device_maps(4).

		      type	Specifies the device type. The value is device-type as described in device_allocate(4).

       -d	      Displays the system-supplied default attributes for the device types managed by device allocation. If dev-type is specified,
		      it lists the default attributes for only that device type.

       -w	      This option can be used with -a to list the current owner of the device as the key value pair owner=value. value is the  uid
		      of  the current owner of the device. If the device is unallocated, value is /FREE. If the device is in error state, value is
		      /ERROR. This option also suppresses any diagnostic output.

       -z zonename    When specified with the -l option, lists only those non-allocated devices whose label range includes the label of the  zone-
		      name, and of the allocated devices, only those that are allocated at the same label as that of zonename.

		      When  specified with the -n option, lists only those non-allocated devices whose label range includes the label of the zone-
		      name.

		      When specified with the -u option, lists only those devices that are allocated at the same label as that of zonename.

EXAMPLES

       Example 1 Listing All Devices

       The following example lists all devices available to the caller for allocation:

	 % list_devices -l
	 device: audio type: audio 
	 files: /dev/audio /dev/audioctl /dev/sound/0 /dev/sound/0ctl

       Example 2 Listing Attributes of All Devices

       On a system configured with Trusted Extensions, the following example lists attributes of all devices available to the caller  for  alloca-
       tion:

	 % list_devices -al
	 device=audio1;type=audio;
	 auths=solaris.device.allocate;
	 clean=/etc/security/lib/audio_clean;
	 minlabel=admin_low:maxlabel=admin_high;
	 files=/dev/audio1 /dev/audio1ctl /dev/sound/1 /dev/sound/1ctl

       Example 3 Listing Attributes Including the Device Owner

       On  a system configured with Trusted Extensions, the following example lists attributes including the device owner of all devices allocated
       to the user:

	 % list_devices -auw
	 device=audio2;type=audio;auths=solaris.device.allocate;
	 clean=/etc/security/lib/audio_clean;
	 minlabel=admin_low:maxlabel=admin_high:zone=public;
	 owner=1234;
	 files=/dev/audio2 /dev/audio2ctl /dev/sound/2 /dev/sound/2ctl

EXIT STATUS

       The following exit values are returned:

       0	      Successful completion.

       20	      No entry for the specified device.

       other value    An error occurred.

FILES

NOTES

       The functionality described in this man page is available only if  Solaris Auditing has been enabled. See bsmconv(1M) for more information.

       On systems configured with Trusted Extensions, the functionality is enabled by default.

       /etc/security/dev, mkdevalloc(1M), and mkdevmaps(1M) might not be supported in a future release of the Solaris Operating Environment.
